  • Quick Details

    1: DIN 1.6587 steel introduction

          1.6587 is a low carbon, case-hardened (carburized) steel containing 1.8% chromium, nickel and molybdenum. It has sufficient plasticity and toughness, with high yield strength, tensile strength, endurance strength (yield ratio is generally about 0.85).

    4: DIN1.6587 steel mechanical properties

        The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.
